What is the significance of security policies in FortiNAC?

Security policies in FortiNAC play a crucial role in managing user access and device security within the network. They define the parameters and rules by which users can connect to the network, determine what resources they can access, and establish the security posture required for devices to be compliant. This ensures that only authorized users and secure devices are granted access, thus mitigating potential security threats and vulnerabilities within the network environment.

By enforcing these policies, FortiNAC can effectively manage device visibility and control, monitor network activities, and respond to security incidents in real-time. This foundational aspect of network security management makes it vital for organizations to have well-defined and implemented security policies that align with their overall security strategy.
